The efficient and regioselective synthesis of various bisheterocyclic compounds was performed using a regioselective onepot lithiation-transmetallation-cross-coupling of α-methoxypyridine.

C-6 lithiation - cross-coupling of heterocycles - 2-methoxy-6-(tributylstannyl)pyridine - 6-bromozinc-2-methoxypyridine
